a\nshared program between the wildland fire management programs of the U.S.\nDepartment of Agriculture's Forest Service, U.S. Department of the Interior's\nGeological Survey, and The Nature Conservancy.\n\nLandfire (LF) Historical fire regimes, intervals, and vegetation conditions\nare mapped using the Vegetation Dynamics Development Tool (VDDT).\nThese data support fire and landscape management planning goals in\nthe National Cohesive Wildland Fire Management Strategy, the Federal Wildland\nFire Management Policy, and the Healthy Forests Restoration Act.\n\nVegetation Condition Class (VCC) represents a simple categorization of the associated Vegetation Departure (VDEP) layer and indicates the general level to which current vegetation is different from the simulated historical vegetation reference conditions.\nVDEP and VCC are based upon methods originally described in Interagency Fire Regime Condition Class Guidebook, but are not identical to those methods.\nFull descriptions of the methods used can be found in the VDEP product description.\nUsers should review those methods before comparing VDEP or VCC values across LANDFIRE (LF) versions.\nVCC is a derivative of the VDEP layer.\nIt is important to read and understand the characteristics of the VDEP spatial product, particularly if VCC values are compared across versions as the VDEP methods varied which directly impacts across-version VDEP and VCC comparability.\nIn LF 2012, the original three VCC classes were divided in half to create six VCC classes to provide additional precision.\n\nThe LANDIFRE Fire datasets include:\n\n- Fire Regime Groups (FRG) is intended to characterize presumed historical fire regimes within landscapes based on interactions between vegetation dynamics, fire spread, fire effects, and spatial context\n- Mean Fire Return Interval (MFRI) quantifies the average period between fires under the presumed historical fire regime\n- Percent of Low-severity Fire (PLS) image quantifies the amount of low-severity fires relative to mixed- and replacement-severity fires under the presumed historical fire regime and is defined as less than 25 percent average top-kill within a typical fire perimeter for a given vegetation type\n- Percent of Mixed-severity Fire (PMS) layer quantifies the amount of mixed-severity fires relative to low- and replacement-severity fires under the presumed historical fire regime, and is defined as between 25 and 75 percent average top-kill within a typical fire perimeter for a given vegetation type\n- Percent of Replacement-severity Fire (PRS) layer quantifies the amount of replacement-severity fires relative to low- and mixed-severity fires under the presumed historical fire regime, and is defined as greater than 75 percent average top-kill within a typical fire perimeter for a given vegetation type\n- Succession Classes (SClass) layer characterizes current vegetation conditions with respect to the vegetation species composition, cover, and height ranges of successional states that occur within each biophysical setting\n- Vegetation Condition Class (VCC) represents a simple categorization of the associated Vegetation Departure (VDEP) layer and indicates the general level to which current vegetation is different from the simulated historical vegetation reference conditions\n- Vegetation Departure (VDep) indicates how different current vegetation on a landscape is from estimated historical conditions. VDep is based on changes to species composition, structural stage, and canopy closure.\n\n### Bands\n\n\n**Pixel Size**\n\n30 meters\n\n**Bands**\n\n| Name | Pixel Size | Description |\n|-------|------------|----------------------------|\n| `VCC` | meters | Vegetation Condition Class |\n\n**VCC Class Table**\n\n| Value | Color | Description |\n|-------|---------|-----------------------------------------------|\n| 1 | #38a800 | Very Low, Vegetation Departure 0-16% |\n| 2 | #4ce600 | Low to Moderate, Vegetation Departure 17-33% |\n| 3 | #ffff00 | Moderate to Low, Vegetation Departure 34-50% |\n| 4 | #ffaa00 | Moderate to High, Vegetation Departure 51-66% |\n| 5 | #ff0000 | High, Vegetation Departure 67-83% |\n| 6 | #a80000 | Very High, Vegetation Departure 84-100% |\n| 111 | #0000ff | Water |\n| 112 | #c8ffff | Snow / Ice |\n| 120 | #8400a8 | Non burnable Urban |\n| 121 | #f516b6 | Burnable Urban |\n| 131 | #4e4e4e | Barren |\n| 132 | #b2b2b2 | Sparsely Vegetated |\n| 180 | #df73ff | Non burnable Agriculture |\n| 181 | #e8beff | Burnable Agriculture |\n\n### Image Properties\n\n**Image Properties**\n\n| Name | Type | Description |\n|-------------|--------|--------------------------------------------------|\n| VCC_classes | DOUBLE | Class values of the Vegetation Condition Class. |\n| VCC_names | STRING | Descriptive names of Vegetation Condition Class. |\n\n### Terms of Use\n\n**Terms of Use**\n\nLANDFIRE data are public domain data with no use restrictions, though if modifications\nor derivatives of the product(s) are created, then please add some descriptive modifier\nto the data set to avoid confusion.\n\n### Citations\n\nCitations:\n\n- The suggested way to cite LANDFIRE products is specific to each product,\n so the model for citation is provided, with an example for a particular product.\n Producer.
